‘63 Century Resorter 19 water pump impeller -I have the Buick 401 “nailhead”engine with a Sherwood water pump but cannot find anything marked on it to tell me what impeller it needs. This is my first old wood boat and boat has sat for 2 years and I’m certain the impeller needs replacing. Anyone know which impeller this Sherwood pump takes or could possibly direct me to a resource that can help me find it?
